"Portrait of William Pitt, 1st Earl of Chatham" by Jean André Rouquet at the Victoria and Albert Museum, London - More commonly known as William Pitt the Elder (to distinguish him from his son William Pitt the Younger), this was the British Secretary of State during the Seven Years War and many victories have been attributed to his policies. This is why, for instance, when the British took Fort Duquesne from the French, they renamed it Fort Pitt - now the city of Pittsburgh, Pennsylvania.

John Pitt, 2nd Earl of Chatham, by George Romney, scanned from 'House of Pitt' by Sir Tresham Lever (1947). This is the portrait on which Jacqui Reiter's excellent drawing is based (pinterest.com/...). It hangs, or used to hang, at Chevening, formerly the home of William Pitt's biographer Earl Stanhope.
From the website: "William Pitt the Younger is dressed in a dark blue coat with brass buttons and a white neckcloth. He also has powdered hair. This portrait of the former Prime Minister is copied from a work by Gainsborough Dupont, the nephew of Thomas Gainsborough. It is one of numerous portraits of Pitt by Dupont, which are all thought to be based on an earlier, original, painted by Gainsborough himself. Gainsborough’s original work is now untraced."

"John Montagu, 4th Earl of Sandwich" by George Townshend (1751-1758) at the National Portrait Gallery, London - I knew that George Townshend was a skilled caricaturist from looking at the various sketches he made of Major-General James Wolfe as one of his brigadier-generals in Quebec 1759. I should get to pinning some of those, by the way. But this is my first time seeing one of his earlier pieces - and they really are quite comical in their simplicity.
